IMPROVEMENT IN REFRIGERATORS.

Speciicationforming part of Letters Patent No. I89,990, dated April 24, 1877; application filed July 7, 1876.

To all 'whom it may concern:

with an ice-chamber having an upper air-inlet` and lower air-outlet, and an4 air exhausting and forcing device varranged to draw the warm air uniformly into the upper chamber, and to cause it to pass into the ice-chamber, so as to produce a gradual downward circulation through said ice-chamber, to and through the lower cooling-chamber. By this construction of the apparatus the cooling-chamber is kept Yof nearly uniform temperature throughout,

and a material economy of ice is secured.

Figure l is a vertical sectional view of a refrigerator made according to my invention. Fig. 2 is a horizontal sectional view of the same. y

The bottom a, sides b, and top c of the refrigerator are, by preference, made double, and lined with non-conducting material, of any usual character, and the refrigerator or refrigerating apparatus is to be of dimensions suitable to the material to be received or transported, and to the quantity of ice employed.

galvanized iron.

The ice-chamberf is separated from the cooling-chamber g by a partition, h, preferably of Above the cooling-chamber g there is a circulating-chamber, r, that is separated from g by a perforated partition, s. The blower t, that is driven by a suitable shaft and pulley, u, or otherwise, is provided with a suction-pipe, c, connecting with the lower part off, to draw air from the air-space r by the suction of the fan-blower through the icechamber, and finally out from the blower at w, so that the air is caused` to circulate continuously through the respective chambers r' and g and the ice-chamber f.

What I claim as my invention islv. The combination of the cooling-chamber g, an air distributing and circulating` chamber of nearly equal horizontal dimensions, situated above, and separated from it by a perforated partition, s, an ice-chamber having an upper air-inlet extending its entire width, or nearly so, and a lower air-outlet communicating with an air exhausting and forcing device, substantially as and for-the purpose set forth.

2. The cooling-chamber g, and the circulating-chamber r in the upper part thereof, separated by the partition s, that is perforated throughout, in combination with an ice-chamber and a blower, which latter causes a con tinuous circulation of air throughout the cooling and ice chambers, substantially as set forth.
